This invention relates to improvements a bed by swinging the seatoutwardly and M downwardly, "thereby extending a .foldable bed framewhich is enclosed Within the box like base of the davenport when made upfor day use. g i

The davenport bed of the present disclosure is typical of the style inwhich the bed is arranged at right angles to the back of the davenport"with thehead at the outer end and in order to obtain full bed lengthand-yet maintain a compact construction" it has been the practice tolift or remove the back restfso as to utilize the available space forthe foot of the bed. H'eretofore it has been necessary to raise the backrest bodily by hand and independently of thebed extending operation, andhence involved considerable physical exertion, although it was possibleto decrease the weight of'the back rest by using lighter springs andupholstery.

The object of the present inventionis pri marily that of-provi ding aconstruction in which the back rest is raised and lowered automaticallywith the extension and folding of the bed frameythereby eliminating 'theadditional efiort and often] laborious task of lifting the same by hand,,And seeondarily it has made possible the use of a more substantial backrest construction including deeper springs and thicker upholsteryinasmuch as'the added weight is flno longer an appreciable factor in themanip ulation of the bed.

The foregoing, together withffother improved features ofconstructionyare fully disclosed in the accompanying drawings, in which1 I Figure 1 is a perspective View of a davenport bed embodying myinvention. 7

Asshown in Figure 1,the davenport bed in its outward appearance istypical of furniture .of this classynamely an elongated sofa with'sidearms 1, 1, back-rest 2, and seat, the latter preferably consisting of acovered seat frame 3and two removable seat cushio'nsh. j

I As is customary in furniture construction, the davenport frame is ofwood, the members being] assembled in skeleton form and then covered orupholstered in the usual manner, with certain portions built upw'ithpadding and backed by springs, as'in the a case of the back-rest.

Without going into detail as tothe frame construction, it consistsgeneral'ly of a rectangula'r base frame 5 extending around the "bottomwith the short legs 6 secured at'e'ach corner. At each end ofthe baseframe are Figure 5 is an enlarged perspective view end frames not showninfull, but on which are built up the side arm s 1, 1.

The back-rest -2,. -a lthough'supported by,

jthe' back' frame 7, is a separate structure and movable relativethereto in a vertical the back-'restfis also an upholstered frame madeup of vertical end frame members 8, 8,

A; back, frame 7 madeup of top and bottom rails to backand extendinghorizontally between 7 "the end members. The lower'rail' 10 is 10- catedsubstantially midway the upper and I p lower ends of the side membersand marks Q the flower extremityf of the upholstering,

which'consists of a backing of coil springs 11 enclosed within a fabriccasing 12tapering to a point at the apex of the L-sha'ped I top rail andhaving the fabric tacked at its 1 lower edges to the edges ofthelowerrail 10.

8'5 direction. Thus as showncin Figures3and 1 Extending verticallydownward from the upper portion of each side frame member 8 from a pointjust below the lower rail 10 is a narrow rail or extension 8aterminating just above the bottom edge of the bottom frame 5, and lyinginwardlyfrom the ends thereof, it being noted from Figure {t that theupper upholstered end portions of the back-rest 2 are extended outwardlybeyond the end frame members 8, 8 to provide extensions which over-liethe rear ends of the arm rests 1, 1 as shown in Figure 1.

These vertical. extensions or rails 864 at each end of the back-resthave sliding connection with a pair of inwardly facing guide members 14,l-l which have the form of metal channel plates flanged at thelongitudinal edges and screwed to the inside faces of the horizontalside frame members of the davenport frame, these members 15 extendinghorizontallyfrom front to rear just below the lower rail 10 of thebackrest 2 (Figure Thus in the lowered or normal position of theback-rest it is supported by the back frame 7 with the top rail 9 of theformer resting on the top rail of the latteiyand the channel plates 14,14 in sliding engagement with the upper end portions of the extensions8a, 8a. The means for effecting raising and lowering of theback-restwill be presently described. I

, Referringjnow to the extensible seat and bed frames, Figures 2 and 3,the former, already identified as a rectangular covered frame, issuitably padded on its top surface as at 8a to provide a resilientsupporting surface for the cushions 4, 4. In the normal position asshown in Figures 1 and 3. the seat frame extends the full width ofthebase frame 5, with its front frame member resting edgewise upon thefront member of said base frame, and having hinged connection therewithby an arrangement of links and levers at either end; each consists ofthe following partsi On the inside face of the front frame member 5m ofthe base base frame is fixed a bracket 16 having an inwardly projectingweb to which is pivotally connected the end of a lever 17, havingsomewhat the shape of a bell crank lever, and having its outer endconnected with one end of another lever 18 pivotally connected with abracket- 19 secured to the inside bottom edge of the seat frame justinwardly from its front edge, Figure 2. Also pivotally connected withthe bracket 16 is a straight lever 20 connected at its one end withanother lever 21, also having pivotal connection with the bracket 19 onthe seat fram Thus the seat frame is hinged to the base frame by twopairs of levers at each end, each pair varying in length and with theirpoints of attachment with the brackets 16 and 19 offset from each otherso as to control the movement of the seat frame as it is being swungfrom closed to extended position. As shown in Figure 2, the seat frame 3after it has been extended, occupies a horizontal reversed position infront of the base frame 5, with its front edge spaced. a few inchestherefrom. In short, the arrangement of levers permits the seat frame toswing t-hro gh 180 degrees, the same time throwing it outwardly from thebase frame, thereby adding severa inches to the length of the bed framesupporting structure.

The bed frame 22 in the extended position shown in Figure 2 is elevateda foot or so above the seat and base frames, and is supported therebythrough a series of levers presently to be described, whereas the outerend of the seat frame is supported by folding legs which also will bedescribed in due course. 1

Referring to the bed frame, the same consists of longitudinal andtransverse metal frame members of angle sections supporting a yieldablelattice or net work of wire or metal strips, af the manner of the ordinarybed or cot Line. The extended frame is full bed length and the widthequal to the width of the davenport.

As already indicated, the bed frame is foldable lengthwise from itsextended position in which its head end projects beyond the outer end ofthe extended seat frame to something less than one-half its length, thatis, the width of the space within the base frame 5 into which it isfolded when the davenport is made up for day use. Thus the longitudinalframe members of the bed frame divid d into four hinged sections fromfoot to head, namely, a short section 23 hinged at its free end to thehorizontal side frame member 15 adjacent the back of the davenport, along section 24:, another short sect-ion 25 and a second long section 26at the head end, the several sections on each side being oivotallyconnected together at their ends through the medium of overlappingextended ears at the ends of the vertical webs of the sections, as shownin Figure 6, thus bringing the ends of the horizontal. webs abuttingcontact when the sections are flexed to a straight line position. Theshort well as the long sections differ in reugth; the section 23 at thefoot being slightly longer than the intermediate short secti n 25, andthe long section between the two s iort ones being longer than thesection 26 at the head or outer endof the bed frame. he reason for thesedifferences in length of sections is necessary to permit the bed frameto fold properly within the'space at the bottom of the d'avenport frame,as will presently be shown. I

The bed frame is supported by three sets of levers arranged in pairsalong the opposite longitudinal and sectionalframe members, one pair 27being pivotally connected with the bracket 16m the 'frontof the baseframe and connected with the sections 24 at a distanceinwardly'from'their outer ends so vthat they stand in substantiallyvertical position when the bed frame is extended; a secondpair oflevers-28 are-connected-with theseat frame substantially midway of itssides and are connected with the intermediate short section nearitsouter end. so that the links'stand upright and incline outwardlyslightly; and finally a third pair of levers 29 pivotally connected withthe'outer bed frame sections 26 just inwardly from the head end, andstand substantially parallel with the intermediate pair of levers 28.

The outer pair of links, however, are not connected directly with theouter end of the seat frame 3, but indirectly through an in'-,

termediate assembly of links which include the. drop le s for said seatframe} This" linka 'e is clearl shown in Fi ures 5 and 6 b o i a (IIIandwill now be described:

At each outer corner of and secured to the faces of the frame membersthereof is an L-shaped plate 30' which in the extended and reversedpositionof the.

seat frame faces upwardly. The plate is provided with an angular web 30alying against the inside face of the end member of the seat frameand atits end is an upright car 305 to which-one end of a curved slotted.lever 31 1S pivoted, this lever extending outwardly toward the frontedge of the seat frame where it'terminates in an ear 31a bent inwardlyat right angles andabove the upper end of a leg bar, 32 pivotallymounted at-32a to the face of a web 38"integral' with the corner plate30" and spaced a short distance awayfrom the vertical front edge 'of theseatframe, said web having an arcuate slot 33a of 90 concentric with thepivot pin 32a. .The upper end of the leg bar 32 is connected with theear 31a of the curved lever 31 by ashort link 34, these partsallswinging in vertical planes'so'tha't'movement im oarted to the curvedlink swings the leg bar f in contact with the floor (Figure v5) to 'ahorizontal position along the edge ofv the ,seat frame. (Figure (3), thelatter poslt on being assumed when the seat frame is closed, so that theleg is concealed.

lPivotally connected to the vertical "web,

30a of the corner plate 30 near itsouter corner is a lever 35 lyinginside. of thesion of thebed frame.

the seat frame '3 rom 'a' vertical supporting position curved lever 31and carrying at a point inwardly from its free ends a stud 35w generalhorizontal direction toward the supporting lever 28 located inwardlyfrom the end of the bed frame and is-pivota'lly con- Y -nected with thesame substantially midwayof its ends. And finally the outer framesupporting lever 29 heretofore identified as pivotally connected nearthe end of the bed frame is pivotally connected at its lowerv end withthe lever 35 substantially midway of its ends. The action ofthisarrangement of levers and links will be explained later in: connectionwith the folding and exten- As previously pointed out, the back-rest 2is connected with the bed frame and slides upwardly and downwardly asthe latter is extended and folded. Figures 2 and 3, this connection isspecifically between each side frame member 8 of the back-rest and theadjacent inner end sections 2330f the bed frame, the latter having atriangular shaped plate 38 fixed thereto and extending at rightanglesito' provide an arm to the end of which is pivotally connected oneend of a connecting link 39, the other end being con'nected with the endof a strap 40 fixed to the inner face of" side frame member 8 just belowthe rail 10.

"To complete the essential parts: of the assembly, a pair of long coilsprings 41, 41

extend from the inner corners of the bedframe downwardly alongthesidesof the davenport' end 'frames'to the first pair of, supportinglevers 27 for the bed; frame, For 1 As shown in v attaching the ends ofthe springs 'to these parts,"aplate 42' is fixed to the extreme ends ofthe bed frame sections 23, and the levers 27 provided with short arms27anear their points of pivotal connection with the brackets 1'6, saidplates 42 and ar1ns'27a having holes punched therein-through which theends of the springs arefhookedt These "springs are normally undertension, but-are I elongated when the bed frame is extended from foldedposition and thus oppose the V unfolding or extension of the bed frameand assist in the folding thereof. H

Supported upon the bed frame isa mattress 43 of standard quality andthickness and'of thesame dimensions as the bed" fra1ne. At the outer endof the bedframe 'isoa pil-ji low rest or adjustable head board-d44, I 1

consisting of a flat cross bar 44wextending betweenthe ends of a pair oflever arms 44b pivotally mounted on opposite sides-of f the .bed frameand on the outer faces' of the sections 26, 26. A spring 45 connectingthe i lower end 'of'eachlever with; the bedframe Y serves" tohold theheadboard in raised position 'ust be 0nd and above the outer end of themattress. This'head board is adapted to be swung inwardly and upon themattress when the bed frame is about to be folded, thus aiding inholding the mattress in place.

A clear idea'of the position of the several moving parts of the assemblyin folded and extended pos'tion as well as their path of movement wil behad from a comparison of Figures 2 and 3 and Figures 5 and 6. Figure '3shows the parts before the bed is extended and thedavenport made up forday use. It is first to be observed that the back-rest- 2 is in itslowered position with its top rail 9resting upon the upper rail 7a ofthe baclrframe 7, and, secondly, that the'bed frame is folded back uponitself, with the several hinged sections constituting the side framesarranged in the general form of a hollow rectan le, that is, the inneror foot section 23 is dropped to a vertical position, the two longersections 24 and 2S extending horizontally in parallel spaced relationwith the shortest section 25 extending crosswise of their ends. Themattress 43 is folded double and lies within the space formed by the bedframe sections, While the seat frame rests on the folded bed frame andthe cushions 4: upon theseat frame.

vTo convert the davenport into a bed the cushions t are removed, and bygrasping a loop 46 attached to the rear edge of the frame and pullingforwardly, said frame is swung upwardly and forwardly by the levers 27.Simultaneously with the movement of the scat framethe bed frame beginsto unfold accompanied by a combined endwise shifting and liftingmovement as the sets of levers 27, 28 and 29 supporting the bed frameflex the sections thereof into a straightened position, the innersections 23 alone remaining in the same relative locations except forswinging through a 90 angle from vertical to horizontalposition as theirouterends are shifted with the parallel movement of the sections24.lhese inner end sections 23being connected with the vertically slidingback-rest through the arm 38 and link 39 slides the latter bodilv alongthe back frame 7 so that its lower end is lifted well above the level ofthe mattress 43, thus permitting the space occupied by the back-rest tobe utilized and extendin the bed to the back frame.

' .When the seat frame 3 has been swung upwardly into an uprightposition the grasp is then shifted fromthe loop 46 to the outer edge ofthe bed frame and from that point on the effort is exerted in a forwardpull until the bed frame reaches its fully cxtended position as shown inFigure 2. It is not thought necessary to trace the swinging movement ofthe-several groups of links and levers, inasmuch as they swing upwardlyand downwardly with the seat and bed frames, their length and points ofconnection determining the path and final relative positions oftheseveral parts. The linkage connecting the outer ends of the frames,however, manner in which the leg-bars 32 are dropped to support theextended structure:

As the seat frame approaches its extended horizontal position in itsoutwardly swinging movement, the end frame is moving relative thereto inan upward and outwardly direction as already explained, and hence thelevers 28 and 29 between the bed and seat frames swing outwardly from asubstantially horizontal position to a vertical position between the twoframes as shown in Figure 5. Thus lever 28 swings in a counterclockwisedirection (to the left) shifting the cross link 37 in the same directionwhich in turn rocks the intermediate lever 35 toward a verticalposition, and sliding the stud 3564 along the slot 36 in the curvedlever 31, thereby lifting its outer end to lower the leg-bar 32 intovertical position through the short connecting link 34. In the meantimethe lever 29 connected with the outer end of the bed frame and with theintertermediate levers unless there is movement of the seat frame. Inshort, the relative positions of the parts as shown would occur as theseat frame is being swung over into closed position and not in fullyextended position, and hence the seat frame is not in the same positionas in Figure 5, but in reality should be reversed. But owing to thedifficulty of clear illustration, the same perspective has been used butwith the bed frame and levers shifted relative to the seat. Thus in theoperation of folding the bed frame the levers swing toward a horizontalposition and to the right, the curved link being depressed by themovement of the stud 35a to the far end of the slot 36, thiscausing theleg-bar 32 to be swung upwardly into horizontal position along the rearedge of the seat frame and which in the closed position of the davenportis entirely concealed.

From the foregoing, it will be seen that the present davenport bedconstruction unites all of the moving parts in such a manner that theyshift together into their proper positions under physical effortappliedat one point, and further that advantage has been taken of leverage inthe design of theconnecting linkages in order'to reduce the exertion ofoperation to a minimum.
